Access control in TPM often requires finer granularity than standard Salesforce Record Sharing allows. While you can use Sharing Rules (Option A) to control visibility of Product records, it becomes difficult to manage complex matrices (e.g., User A sees Beverages for Customer X, but Snacks for Customer Y) and can impact system performance if rules become too complex.

The purpose-built solution in Consumer Goods Cloud TPM is User Settings.

Within the TPM administration, you can define specific Managed Products (or categories) and Managed Accounts for each user.

Configuration:The consultant navigates to the User Settings for the KAM.

Assignment:They select "Beverages" in the Product definition section.

When this KAM logs into the TPM Planning Grid (P&L), the application logic reads these User Settings and filters the data query. The KAM will simplynot seeany products outside the Beverages category. This is a functional application-level filter that ensures the planning environment is tailored to their specific responsibility, making Option C the recommended best practice over the broad platform-level sharing rules.
